Crate rten_imageproc

Expand description

Provides 2D geometry and image processing functions.

This includes:

2D vectors and related math
2D shapes and associated algorithms: Point, Line, Rect, RotatedRect, Polygon
Rudimentary drawing functions
Algorithms for finding the contours of connected components in an image (find_contours)
Algorithms for simplifying polygons and finding various kinds of shape that contain a polygon: simplify_polygon, min_area_rect, convex_hull

Structs§

FillIter: Iterator over coordinates of pixels that fill a polygon. See Polygon::fill_iter for notes on how this iterator determines which pixels are inside the polygon.
Line: A bounded line segment defined by a start and end point.
Painter: Painter is a context for drawing into an image tensor.
Point: A point defined by X and Y coordinates.
Polygon: Polygon shape defined by a list of vertices.
Polygons: A collection of polygons, where each polygon is defined by a slice of points.
Rect: Rectangle defined by left, top, right and bottom coordinates.
RotatedRect: An oriented rectangle.
Vec2

RetrievalMode: Specifies which contours to extract from a mask in find_contours.

IMAGENET_MEAN: Standard ImageNet normalization mean values, for use with normalize_image.
IMAGENET_STD_DEV: Standard ImageNet normalization standard deviation values, for use with normalize_image.

BoundingRect: Trait for shapes which have a well-defined bounding rectangle.
Coord: Trait for types which can be used as coordinates of shapes.

bounding_rect: Return the bounding rectangle of a collection of shapes.
convex_hull: Return the sorted subset of points from poly that form a convex hull containing poly.
draw_line: Draw a non-antialiased line in an image.
draw_polygon: Draw the outline of a non anti-aliased polygon in an image.
fill_rect: Fill all points inside rect with the value value.
find_contours: Find the contours of connected components in the binary image mask.
min_area_rect: Return the rotated rectangle with minimum area which contains points.
normalize_image: Normalize the mean and standard deviation of all pixels in an image.
simplify_polygon: Return a simplified version of the polygon defined by points.
simplify_polyline: Return a simplified version of the polyline defined by points.
